The drawing, Figure 1, shows the envelope afterit has been cut from a single sheet of paper. All portions marked G represent gumming. The dotted portion marked W represents a portion of the envelope which has been cut or died out In the making of this envelope, a single sheet of paper is first cut to conform to the figure shown in the drawlng F1gure 1. The figure so cut is then'gummed on all portions marked G. The gumming 1s placed on one side of the envelope only. The section W is then out out, and the envelope'ls also out along the two lines 7. The section E.is then folded along the line 4 up and over the section D and glued in 1 place by the portions G on section D.

The portion thus folded is then folded along the line 5 u and over the section C. The section is then folded along the line 2 down and over the portion already formed. It is glued in lace by the port on marked G from the right edge of section B to the line on the right numbered 7 and from the left edge of section B to the line on the left numbered 7. The flap or tongue A formed on the free edge of the flap B is then folded back and up along the line 1 and left free. The flap H is then folded along the line 6 to the right and over the body of the envelope formed by the folding of sections A," B, C and D, and glued in place by the gumming on that flap. The envelope bemg thus formed, third or fourth class mail may be inserted along the line 3 and the flap F folded over and glued or fastened in place by any appropriate fastening device. First class mail may be inserted through the portiori W. The portion for first class mail is sealed by folding the flap A down along the line 1 and gluing same along the gummed portion thereon.
